• Pure Go, static binary without libmagic
• Cross-platform: No unix specific code like mmap

Download from https://github.com/file-go/fil/releases

go install github.com/file-go/fil@latest

Just like unix file command

$ fil <FILE_NAME>

The code is based on toybox (but it is written in C, and only runs on unix-like OS)

1. Port more code from toybox/file.c
2. Port more code from filetype/matchers
3. More magic
